HOLDER FOR MAGNE'IO CONTACTS.

- Application filed December 19, 1919. Serial No. 346,199.

and State of Oregon, have invented certain new and useful Improvements in Holders for Magneto Contacts, of which the following is a specification.

-My invention relates to collector contacts for magnetos of the Ford type, a purpose of my invention being the provision of a device for securing the contact and binding post in proper position upon the crank case in such manner that they can be instantly removed for cleaning or inspection purposes without the necessity of removing screws or bolts as is the case in devices heretofore designed for this purpose.

I will describe one form'of holding device embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawings Fi ure 1 is a view, s owing in perspective one orm of holdin device embodying my inventionin applie position to the contact and binding post of amagneto;

F i ure 2 is a view similar to Figure 1, shown the, device in side elevation and partly in sectionand Figure 3 is a detail view, showing in top plan the clamping plate shown in the precedin views.

Re errin specifically to the drawin in which simi ar reference characters re er to similar parts, K desi ates a crank casein which is housed a 0rd type of magneto (not shown), and extending through the upper side of the crank case is a tubular conductingbushing T which is adapted'to house a spring pressed contact element E,

shown in dotted lines in Figure 2. As in the usual form of bushing, the bushing T is formed at its upper end with a bindin screw B adapted to receive a binding nut 15 for securing a conductor C to the bushing. Snugly embracing the bushing T at a point conti uous to the outer side of the crank case is a disk of insulating material D. l with and dependin from the under si e of the disk D is a co lar A formed of insulating material. The bushing T is adapted to be secured upon the crank case K by a clamping plate P which holds the disk D in firm engagement with the crank case K. As illustrated to advantage in Figure 3, the plate P is of Y-shape formation with a depending lip 15 formed at one end to properly space the adjacent end of the plate from the crank case a distance gprres nding to the thickness of the disk he parallel portions of the plate are formed with depending .fianges 16 which I as shown in Figure 1, are curved to embrace the peri hery of the disk D. The'plate P is secure y heldin engagement with the disk D by a stud S, the lower end of which is secured within the crank case K while its upper end is threaded to receive a winged nut W. As shown in Figure 2,the stud S slidably receives the plate P with the nut W engaging the upper side of the plate and thus holding the same in snug engagement with the disk D. A washer 17 is interposed between the plate and nut to allow free rotation of the latter upon the stud in clamping and unclamping the plate as will be understood.

When it is desired to remove the bushing T'so as to effect: a removal of-the magneto contact, it is obvious that by removing the winged nut\W from the stud S the plate P scribed only one form of holding "device embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of theinvention and thespirit and scope of the appended claims.

Having thus described my invention, I claim f 1. In combinatioma crank case, a magneto contact including a bushing extending through the crank case,a disk carried by said bushing exteriorly of the crank case, a stud secured within the crank case, a plate mounted on said stud and engageable with can be readily removed so as to disengage said disk, said plate being ofY-shape formation, depending flanges formed on said plate and'engageable with the periphery of said disk, a spacing lip at one end ofthe plate, and a nut threadedlymounted on said stud and engageable with said plate for forcing the latter into engagement with said disk.

2. In combination, a magneto contact including a bushing, a disc carried by the 5 bushing, a stud fixed adjacent to the disc, a plate of Y-shaped formation slidably mounted on said stud, depending flanges formed on said plate and engageable with the periphery of said disc a spacing lip at one end of the plate, and a nut threadcdly mounted on said stud and engageable with said plate for forcing the latter into engagement with said disc.
